MODELING AND SIMULATION OF BLAST WAVE FOR PRESSURE SENSOR DESIGN

In this paper a universal model for pressure waves generated by high energy charge explosives and gunshots is developed for determining the pressure vs. time profile (P-T curve) at a given point in space which is useful for design and characterization of pressure micro sensors and explosives etc. The simulation of the model is carried out through virtual instrumentation (VI) using LabVIEW. The technique used to develop the model, in the present work, is similar to the well known statistical technique of structural equation modeling (SEM).The simulated data is compared with the available experimental data sets in terms of Pearson’s correlation and chi-squared goodness-of-fit test (χ2) and they were found to be in close matching. This work can be extended for modeling and characterization of other types of pressure waves.
